How to move iPhone contact list with custom ringtones to OS X server Contacts?

Question

I have recently setup a new Mac Pro, Mid 2012, running Mavericks OS X Server.  I was previously syncing through iTunes on Snow Leopard, 10.6...
Due to the changes in Mavericks WRT iTunes address book syncing, I want to setup Contacts in Server, as I do not want to use iCloud. I tried using the Address Book sync on my MacBook Pro, but that doesn't appear to save any custom ringtone data. I setup Contacts in Server & I moved the current address book to Mavericks, but dragging the contacts into the Server list in Contacts generates warnings, "Some contacts could not be copied to the server"  and then sometimes starts duplicating the groups and contacts. The system log has some errors that seem related (system & user munged):
Jan  1 22:44:46 system.sub.domain Contacts[3203]: Error reading store metadata: Error Domain=NSCocoaErrorDomain Code=260 "The file \u201cAddressBook-v22.abcddb\u201d couldn\u2019t be opened because there is no such file."

AddressBook-v22.abcddb, does exists, T/S of 22:44. Maybe the above is actually a warning that it created the file?  ... except the Failed adding account doesn't sound good.

So the question is:
How to does one move or import iPhone contact list with custom ringtones to OS X server Contacts? ... and will Contacts save/preserve the ringtone settings?
Thanks

lsof is the standard tool for listing open files, although I'm not quite sure it'll do what you want.
It will list every open file used by every process on the machine, including many you don't expect. I don't know how it will present files opened by network users - whether they'll appear as owned by the file sharing process or not at all. Definitely one to try.
